Hi Linus
Spanning tree needs two parts. You need to be able to change the ports
between disabled, blocking, learning, forwarding. And you need to be
able to send/receive frames.
If spanning tree is performed in the ASIC, i don't see why there would
be registers to control the port status. It would do it all itself,
and not export these controls.
So i would not give up on spanning tree as a way to reverse engineer
this.
